Dogen's Soto school taught that sitting in Zazen was entering the flow of each moment by dropping from the mind the concepts of past, present, and future. Life is one and its flow of movements and events should not be held to or dominated to create illusions of permanence. All moments and all actions, whether they are important, insignificant, fascinating, or boring. -- are seen as the actual realization of Buddhahood. The Soto school's Shikantaza helps one realize this moment now. In the Shobogenzo, Dogen said that it was useless to fix one's hopes on a goal.
